DOMESTIC APPLIANCE.

Application filed November 26, 1923.

This invention relates to wringers and has for its object to reduce to a minimum the liability of bending or breaking of wringer springs.

The disclosed embodiment of the invention comprises a wringer including a frame and rolls. The ends of one of the rolls cooperate with pressure blocks slidable in the frame. Two leaf springs, arranged side by side, extend lengthwise in the frame, and each spring is supported at one end by the frame and bears at the other end upon one of the pressure blocks. A common adjusting screw is provided for regulating both springs.

Further objects and advantages of the present invention will be apparent from the following description, reference being had to the accompanying drawing, wherein a preferred embodiment of one form of the present invention is clearly shown.

In the drawings:

Fig. 1 is a sectional view of a wringer embodying the present invention.

Fig. 2 is a sectional view taken on the line 22 of Fig. 1.

Referring to the drawings, a wringer frame receives blocks 21 which support shaft 22 of lower wringer roll 23. Shaft 22 is provided at one end with a gear 24 and extends through an aperture in the side wall of frame 20 and is adapted to receive a hand crank (not shown). Gear 24 cooperates with a gear 25 secured to wringer shaft 26 of upper wringer roll 27 for driving roll 27. Pressure blocks 28 and 29 are guided by frame 20 and engage the opposite ends of wringer shaft 26. v

Wringer frame 20 is provided with inwardly extending lugs and 36 having slots 37 and 38 respectively. One end of a leaf spring 40 is received by slot 37 and the other end thereof engages bearing block 28. Another leaf spring 41, arranged alongside spring 40, has its one end received by slot 38 and the other end thereof engaging bear ing block 29. A bail 42 loosely surrounds springs 40 and 41 adjacent their central portion and tends to maintain the springs in their relative position shown in Fig. 2. Bail 42 is recessed at 43 for receiving the end of an adjusting screw 44 which is received Serial No. 677,169.

by a threaded aperture 45 in the top wall of frame 20.

It will be apparent that upon screwing the adjusting screw 44 into frame 20, pressure will be applied to both of springs 40 and 41 and to pressure blocks 28 and 29, thereby increasing the pressure between wringer rolls 27 and 23.

When clothes are fed centrally between the rolls 23 and 27, the springs 40 and 41 will tend to maintain an even pressure along the rolls. However, for example, when clothes are fed through the. wringer rolls adjacent the right hand end of said rolls, as viewed in Fig. 1, and pressure block 28 is raised upwardly, the benefit of the long spring 40 will be secured to maintain pres sure between said rolls, and there will be less likelihood of bending or breaking of the spring 40. If thin pieces are being wrung through adjacent one end of the rolls and thicker pieces adjacent the opposite end of the rolls, the required pressure adjacent both ends of roll 27 will tend to be supplied by the independent action 0 springs 40 and 41.

Since the bail 42 loosely surrounds the springs, each spring is free to bend substantially through its entire length. Therefore pressure is exerted upon each pressure block by a spring, the operative length of which is substantially the length of the frame. With such aconstruction, there is less likelihood of breakage than in the case where a single leaf spring is employed which bears at each end upon a pressure block.

While the form of embodiment of the invention as herein disclosed, constitutes a preferred form, it is to be understood that other forms might be adopted, all coming within the scope of the claims which follow.

\Vhat is claimed is as follows:

1. A wringer comprising, in combination, a frame and rolls supported thereby, pressure blocks cooperating with opposite ends of said rolls, leaf springs each having one end supported by opposite walls, respectively, of said frame, the other end of each of said springs bearing respectively upon said blocks, and a common member for regulating the pressure of said springs.

2. A wringer comprising in combination,

loo

a frame; bearing members supported at 0pposite sides of the frame; pressure rolls journaled in said bearing members; a pressure block provided at each end of one of the pressure rolls; a leaf spring for each of the said pressure blocks one end of each leaf spring engaging With a pressure block and being free of the frame While the opposite end of each leaf spring is supported in the frame adjacent the opposite pressure block; and a common means forhol-ding the springs together and for regulating the pressure thereof.

In testimony whereof I hereto aflix my signature.

RALPH L. LEE.
